• Define hydraulic: Hydraulic is the study of pressure in liquids.

  • Define pneumatic: Pneumatic is the study of pressure in gases.

  • What are 4 hydraulic devices: Backhoes, bulldozers, excavators and the jaws of life are 4 examples of hydraulic systems.

  • What are 4 pneumatic devices: Tire changing machines, Impact wrenches, air grinders and dentist drills are 4 examples of pneumatic systems.

  • How do hydraulic systems work: In most hydraulic systems, the force is exerted on a continous, enclosed liquid.

  • How do pneumatic systems work: A pneumatic system is any system that uses air pressure to move either a turbine or a cylinder to accomplish some work.

  • What are the major differences between hydraulic and pneumatic: The major difference between hydraulic and pneumatic is hydraulic-pressure of liquid/pneumatic- pressure of gases.
